Install Nokogiri failed

[caishu...@gmail.com]

Hello everyone ,I have a problem when i install metasploit

When i execute the code ' bundle install ' it tells me I should run 'gem install nokogiri -v '1.6.8'' and I did.

But it gives out the error 

ERROR:  Error installing nokogiri:

************************************************************************

IMPORTANT NOTICE:

Building Nokogiri with a packaged version of libxml2-2.9.4.

Team Nokogiri will keep on doing their best to provide security

updates in a timely manner, but if this is a concern for you and want

to use the system library instead; abort this installation process and

reinstall nokogiri as follows:

    gem install nokogiri -- --use-system-libraries

        [--with-xml2-config=/path/to/xml2-config]

        [--with-xslt-config=/path/to/xslt-config]

If you are using Bundler, tell it to use the option:

    bundle config build.nokogiri --use-system-libraries

    bundle install

Note, however, that nokogiri is not fully compatible with arbitrary

versions of libxml2 provided by OS/package vendors.

What should I do? Thanks

Hi,

Maybe try:

xcode-select --install

There is some good info here (a little ways down from the anchor):

Hope that helps

xcode-select is work for me，But the error is still in

[Ivan Reese]

Agh. xcode-select --install fixed it for me. Very strange — I updated the command line tools right after upgrading to Sierra.

[Ivan Reese]

I am also getting this error. I'm attempting to use Nokogiri in Rails. I'm running Sierra 10.12.0. I do not have LZMA installed via homebrew — presumably, the system version should work, no?

Hi, 

Thanks for your solution. 

xcode-select --install which works for me.
